OMIA 002140-9615 : Exercise induced metabolic myopathy in Canis lupus familiaris

Possibly relevant human trait(s) and/or gene(s) (MIM number): 201475

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal Recessive

Considered a defect: yes

Key variant known: yes

Year key variant first reported: 2018

Cross-species summary: (EIMM)

History: Lepori et al. (2018): "To our knowledge, this is the first description of this disease in dogs, which we propose to name exercise induced metabolic myopathy (EIMM), and the identification of the first canine pathogenic ACADVL variant. Our findings provide a large animal model for a known human disease and will enable genetic testing to avoid the unintentional breeding of affected offspring."

Molecular basis: Lepori et al. (2018): "Whole genome sequence analysis of one affected dog and 191 controls revealed a nonsense variant in the [comparative functional candidate] ACADVL gene encoding acyl-CoA dehydrogenase very long chain, c.1728C>A or p.(Tyr576*). The variant showed perfect association with the phenotype in the 10 affected and more than 500 control dogs of various breeds."

Clinical features: Lepori et al. (2018): Clinical signs included "exercise induced weakness, muscle pain, and suspected rhabdomyolysis". Affected dogs have elevated serum creatine kinase (CK) and alanine aminotransferase (ALT) activities. An acylcarnitine profile from blood revealed an elevated tetradecenoylcarnitine (C14:1) peak suggesting the diagnosis of acyl-CoA dehydrogenase very long chain deficiency (ACADVLD).

Pathology: Lepori et al. (2018): "Muscle samples harvested from the affected German Hunting Terriers ... revealed a mild to moderate necrotizing myopathy with enrichment of interfibrillar lipid droplets and mitochondrial abnormalities. Changes were widely spread and more prominent in type 2 fibers. Nerve biopsies ... were unremarkable."

Breed: German Hunting Terrier.

Variants

By default, variants are sorted chronologically by year of publication, to provide a historical perspective. Readers can re-sort on any column by clicking on the column header. Click it again to sort in a descending order. To create a multiple-field sort, hold down Shift while clicking on the second, third etc relevant column headers.

WARNING! Inclusion of a variant in this table does not automatically mean that it should be used for DNA testing. Anyone contemplating the use of any of these variants for DNA testing should examine critically the relevant evidence (especially in breeds other than the breed in which the variant was first described). If it is decided to proceed, the location and orientation of the variant sequence should be checked very carefully.
